Blogger Jack March claims that a new smattering of the laptops will arrive midway through next year that come in space grey, gold and silver colours with a 12in display that compares to the Microsoft Surface Pro 3.

March goes on to quote a source familiar with Apple’s plans as stating that it has a “noticeably thinner design” though no dimensions have so far been provided on the product.

The thinner design means that a standard USB port could be removed and in its place will be a new USB Type C reversible port that will ship inside an Apple device for the first time.

Apple’s MagSafe charging port is another part that is being sacrificed and in its place will be a different way to charge the device though the source wasn’t sure whether this element has been finalised.

The source went on to add that the 12in MacBook Air will be completely fanless to aid the thinner design and the display bezels are thinner as a result and “quite similar” to what is present on the current MacBook Pro Retina lineup.

Another element to see a big shrink in size is the keyboard space with no border around the edge of the keys and the speaker position has been changed to “above the keyboard and visible”.
